下面由composer教程欄目給大家介紹centos7.7安裝php7.3的lnmp環(huán)境和composer詳細(xì)步驟，希望對需要的朋友有所幫助！
1.更新源
yum update
2.安裝nginx
yum install nginx
3.啟動(dòng)nginx
service nginx start
4.訪問http://你的ip
如果想配置域名，見最下面。
5.安裝mysql:
安裝mysql源 yum localinstall http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
安裝： yum install mysql mysql-server
啟動(dòng)： /etc/init.d/mysqld start 或者 service mysqld restart
重置密碼：mysql -u root -p
幾率報(bào)錯(cuò) can't connect to local mysql server through socket '/var/lib/mysql/mysql.sock' (2)
原因：權(quán)限問題
解決： sudo chown -r root:root /var/lib/mysql (兩個(gè)root都可以改為擁有者，但是需要保持一致)
重啟服務(wù)
service mysqld restart
登陸mysql
mysql -u root -p //按回車直接可以登陸，剛安裝完mysql是沒有密碼的
修改mysql密碼
use mysql;
低版本修改：update user set password=password('你的密碼') where user='root';
高版本修改：update user set authentication_string = password('你的密碼'), password_expired = 'n', password_last_changed = now() where user = 'root';
alter user 'root'@'localhost' identified by '你的密碼';
如果說密碼強(qiáng)度不夠，可以查看密碼級別：show variables like "%password%";
然后設(shè)置為低級別：set global validate_password_policy=0;
最后退出；
exit;
重啟 service mysqld restart
允許遠(yuǎn)程訪問
1.必要時(shí)加入以下命令行，為root添加遠(yuǎn)程連接的能力。鏈接密碼為'你的密碼'
grant all privileges on *.* to 'root'@'%' identified by '你的密碼' with grant option;
flush privileges;
2.打開my.cnf文件
添加一行 bind-address=0.0.0.0
3.重啟mysql
6.安裝php
yum install php php-devel //php5.6版本
如果想安裝7.3
首先安裝 epel 源
1.yum install epel-release //安裝 epel 源2.yum install http://rpms.remirepo.net/enterprise/remi-release-7.rpm //安裝 remi 源3.yum install -y php73-php-fpm php73-php-cli php73-php-bcmath php73-php-gd php73-php-json php73-php-mbstring php73-php-mcrypt php73-php-mysqlnd php73-php-opcache php73-php-pdo php73-php-pecl-crypto php73-php-pecl-mcrypt php73-php-pecl-geoip php73-php-recode php73-php-snmp php73-php-soap php73-php-xml 4.php的安裝目錄/etc/opt/remi/php73/ php.ini也在里面
找到php.ini 里面fix_pathinfo 修改成0 但是不能看phpinfo();
操作
systemctl restart php73-php-fpm #重啟systemctl start php73-php-fpm #啟動(dòng)systemctl stop php73-php-fpm #關(guān)閉systemctl status php73-php-fpm #檢查狀態(tài)7.最后在yum update 更新php資源 方便以后更新擴(kuò)展用
8.安裝composer
curl -ss https://getcomposer.org/installer | php73
mv composer.phar /usr/local/bin/composer
這樣輸入composer會報(bào)錯(cuò) ：/usr/bin/env: php: no such file or directory
解決方法
cd usr/bin
cp php73 php
在輸入composer就好了
更改鏡像為阿里云：composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/
9.安裝git
yum -y install git
10.下載laravel框架
composer create-project --prefer-dist laravel/laravel 項(xiàng)目名稱 "6.*"
composer create-project --prefer-dist laravel/laravel laravelxs "6.*"修改composer文件。
cd /root/.config/composer/vi auth.json{"bitbucket-oauth": {},"github-oauth": {},"gitlab-oauth": {},"gitlab-token": {"github.com": "在git上生成的token"},"http-basic": {},"bearer": {}} 添加
"github.com": "在git上生成的token"
11.nginx域名的配置
創(chuàng)建文件：域名.conf
里面的內(nèi)容：
server{listen 80;server_name 你的域名;access_log /var/log/nginx/access.log;error_log /var/log/nginx/error.log;index index.html index.htm index.php;root 你的項(xiàng)目目錄;location / {try_files $uri $uri/ /index.php$is_args$args;}location ~ .*\\\\.(php|php5)?${#fastcgi_pass unix:/dev/shm/php-cgi.sock;fastcgi_pass 127.0.0.1:9000;fastcgi_connect_timeout 180;fastcgi_read_timeout 600;fastcgi_send_timeout 600;fastcgi_index index.php;fastcgi_split_path_info ^((?u). \\\\.php)(/?. )$;fastcgi_param script_filename $document_root$fastcgi_script_name;fastcgi_param path_info $fastcgi_path_info;fastcgi_param path_translated $document_root$fastcgi_path_info;include fastcgi_params;}location ~ .*\\\\.(gif|jpg|jpe
